' In carrymgthis invention into practicet-he 1 roadbed or foundation ofthe railway track is congmsed of longitudinal composite.stringers A: 7

adapted to support the rails Cof the track, see Figs. .1 and 2. Thecomposite stringers are bankeebwith any suitable filling materialtoproduce an embankment D, and between the rails of the track thisembankment may be constructed or fashioned in order to provide alongitudinal gulley or gutter (1'. From this'gutter are adapted toextend transverse drains E,,.the latter running below one of thestringers and discharging the water from the gulley at. any desiredplace away from the'track.

For economy inccnstruction and installation, the com ositestringers A,B, are sepaonly joined by the filling material which constitutes theembankment D; Each composite stringer consists of concrete, or similarlmaterial a, and metal b,for reinforcing said. concrete, thus'producingwhat I term ablebodied concrete. In cross section the rate 'or insta edindividually, that is,f they have no common connection, and they arestringer Azor B may have'any'suitable oridesired contour, one form ofsaid stringer being I may employ any suitable construction orarrangement of metal to form-v the internal strengthening member of thestringer, but, in. one embodiment of said in-a verition," this metallicstrengthening elements is in the form of a skeleton framework, the

same beingshown by Figs. 3 and 4, as consisting of a frameworkwhich 1str angular in cross-sect ongand Y composed of parts: -Wll10ll 1 arejoined bylicoupling pieces. It is to be unt derstood-,;h0tvever, thatthe invention isnot restricted to any particular or detailed-constructiofl of the metal reinforcing member, but it'is believed thatthe particular form of the triangular skeleton framework is -espe-'chair section has a longitudinal noted that the rail rests squarely orl may be employed, as the chanical eouivalents one for the other. Aftercially useful in the construction of the cornposite stringer. The baseportion of the triangular framework is at the bottom of the stringer,and said framework has, at its apex,

'a longitudinal runner 1;, adapted for the reception of a plurality ofchairs Fforsupporting the rail 0.

Each chair F consists of the members or sections f, f-, one of which isshown more clearly by Figs. 6 and 7 The inner portion of the chairsection is rovided with a transverse groove -f and elow this groove thepassage or opening f The chairsectionis, furthermore, provided with alongitudinal slot j", the same being approximately T-sha'ped incross-section, and. opening through the upper face of the chair. Arecess f is provided on said upper face of the chair, said recessforming shoulders f s In the installation of the track, the members), f,of each chair are fitted to the runher I) of the metallic framework 6,so that the groovesf of said brace the aforesaid runner l). Thehectionsof the chair are clamped firmly on the runner I) by a bolt G, whichpasses through the passages f of said chair, and on the end ortions ofthis bolt are screwed the nuts g, t. is latter binding against the chairsections and clamping them firmly on said runner b.

It will be understood that a suitable num ber of chairs F are attachedto the runner b of each' framework forming a part of eachv stringer,said chairs being spaced at proper intervals on the aforesaid runner b,and said chairs being partly exposed above the con crete material. a,for the proper reception of the rail C.

By reference to Figs. 3 and i, it will be upon the chairs and upon theconcrete material a, in the intervals between the chairs, thus affording a permanent and substantial foundation for the rail.

' Any suitable means for holding the rail on the chairs maybe employed,and in Figs. 8 and 9, I have shown different constructions of railclamping devices. In Fig. 8a wedge;

shaped or tapered plate His employed, said plate having, at its lowerrear end, an'oifset or flange h, and said plate having a slot h,

V which opens through one end of the clamp,

thereby producmg what I term a bifurcated wedge or claw. In Fig. 9,another form of tlieclamp is. represented at I, said clamp censisting ofa tapering or wedge-shaped plate having a heelor flange "i, and a sloti. It will be noted that either of these clamps, H

"are the methefrail sheillhavebeen-laid on the chairs, the clamps-arefitted'to said chairs and adjusted to engage with thebaseflange of therail on the respective sides tliereoli, and then the chair sections willsin-- clamps are secured in position by the bolts J, the headsof saidbolts being received in the slots f of the sections of the chair. Thenuts 1' may be ti htened on the bolts to force the clamps tightly intoengagement with the rail.

If desired, after the clamps have been. placed in position, so that theheels'thereof occupy the recesses of the chairs, the bolts may then beti htened,,and thereafter the clamps may be riv eninto. lace for thepurpose of tightly clamping 't erail 11 on the chairs. It will beunderstoodthatt e heels of the clamps fit in 'the' recesses of thechairs, so that the shoulder f wil revent the clamps from. moving outwary and away from the rail.

In installing a track in accordance with this invention one mode ofprocedure is as follows :--The grade being established, I spread a layerof suitable material, such as cement concrete; in suitable pro )ortionsbelow the position to be assumed by each rail of the t rack.- On thislayer, and in correct position, the framework is placed, and anotherlayer or charge of cement is then dumped upon the first layer'so as tosurround or envelop, substantially, the skeleton framework. -On thislayer a plank or board is placed on each side of the embryo stringer soas do constitute a temporary form for the concrete material, thusenabling me to resume and complete the operation of installing theconcrete matcrialfor the stringer. The concrete material is leveled offand accurately finished so as to produce the permanent longitudinalcomposite stringer, and, at the proper time, the chairs F are fitted orapplied to the memberbof the framework. As the top portion of theconcrete material forming a part of each stringer is intended to besomewhat above the upper sustaining member I) of the skeleton framework,I employ temporary twin blocks (not shown) which are the exactcounterpartof the chairs, said ten'iporarjr twin. blocks being set inthe cement, well as fitted on the up )er portion of the cement formssoas to be ush with the top. 'lhesc temporary twin blocks are employedwhile the work of finishing and leveling the upper portion of theconcrete is in progi less. As the concrete materials set and becomehardened, the twin blocks are removed, and the inenibers'of the chair Fare inserted on each side of the composite stringer, said chairsengaging with the member 3) of the skeleton framework, and being clampedfirmly thereto, as heretofore described. It will be noted that themembers of the chair are partly embedded or incased by concretegnaterial of the stringer, that said chair is clamped firmly to themember 6, and that the uppor faccs or seats of the chair aresubstantially flush with the accurately finished top surface of theconcrete material.

' Inthe embodimentof the invention shown by Figs. 19w inclusive, which:iPiesent a good substantial, constriiction. of reinforced concretecontinuousdwarfed walls constitutshown, nor V o I consider]itnecessaryto show, the employment of the:usualcrossftiesv in thisstructure. .Nevertheless, prov1s1on may be madeforsucli-ties, shouldconditions,

require them.. I have shown. however, in

Figs..,3, 4 and 5, oneforin of'crose tie or cross connection betweenadjacent chairs .011; the

parallel-stringers. Said cross-tie or cross connection may consist of alength of tubular metal K. Thiscross-tie isreceived inlthe'projectionsk' at the lower part .ofthe chairs,"

J and it is 'heldor'secured in place byiany suitable means. The crossconnection is intend- 'ed to be incased or embedded permanently, as

at 7r, by concrete material,- and this concrete;

material may have any desired form in cross-' section, andit mabemolded, or formed by. an appropriate mo d or former'which may beindependent of the temporary former for the stringers, or may beemployed in. conjunc tion therewith. It is evident thatthecros'stie- Kmay be insertedin the passages f of the chairs, in whicheventthe boltsmay be omitted, and, in lieu, thereoffthe tubular '30 bolt K beemployedand another en be passed all. the way cross-ties J map .may t throughthe tubular cross-tie fittin'g, the said bolt being fastened with thesame nuts on the outside ofthe walls a." This construction provides acompletefcross tie connectionat-a very moderate cost, and itcanbeinstalled andprotec'ted from the weather by thecon-x crete materialquite expeditiously and -'eco- From thexforegoing description taken inconnection with the drawings, it will, be noted that the stringers areshown as oblong or square in cross-section forthe reason that such aform of stringer or girder is Well adapted for supportingtherail-chairs, but it will be understood. that the dimensions of thestring ers or girders, and the size ofthe skeleton framework, may bemodified and varied as cond1t1ons may require.

In some instances where an unusually strong strmgeror girder isrequired, I prefer to em loy a larger skeleton framework, the sustainingmembers whereof may be of solid iron bars, but, in any 'event, theskeleton framework will of itself extend over fairly wide spaces and beself supporting,f while the operation of fillingin' the concretematerial is being completed, so that the entire construction of the newroadbed can be perfected from'endto end with the same materials. I t

As hereinbeforeindicated, the stringers-or girders may be graded in anyway familiar to, or preferred by, those skilled in railway trackinstallation. As shown by Fig. 1, the emif bankment may consist of goodheavy soil or other ballast, the space between rails can be utilized forwater troughs, and said space can be well filled in and topped off withcement, as shown, so as to formsaidtroughs, or mg the com 0811361stringers, I have not toprovide'gulleys which may be drainedadvantageously by the transverse drain or by any other suitableconstruction.-

.In and 11 of the drawings I have re resentedan embodiment of theinvention w erein the composite stringer is.used in connection with aform of chair adapted for supporting a bisected and reversible rail, thelatter being of the character disclosed in a I prior. application filedby me on "March 20, .1905, Serial No. 251,181 As shown, the bisectedrail 0 consists of matching members which. are recessed on their innerfaces and are provided at their top and bottom edges with complementalrail heads,- thus enabling the sections .or lengths of the rail to bere- .versed edge for edge, and end for end, for-the u-rpose ofpresenting newwearing surfaces or engagement with the wheel flanges ofthe rolling stock. The sections'of the chair F are recessed on theirinner faces to engage with the side portions of the rail sectionsalong-the foot flange and the webs thereof,- and these chair sectionsare, also, recessed on their inner faces for engagement with thestringer b of the skeleton incased frame 6.

1Tl1e chair sections are, furthermore, provided with transverse oeningsor passa es J, in which are receive the clamping bo ts G, G,whereby the sections of'thechair F may be clamped firmlv upon the memberb of the framework, said bolts G, G extending through the chair sectionsabove and be low the member b, respectively.
